To all whom it may concern:

Be it known that I, WILLIAM H. ALBACH, a citizen of the United States,residing at Mansfield, in the county of Richland and State of Ohio, haveinvented certain new and useful Improvements in Turnbuckles, of whichthe 2o far at least as it serves as a means for tightening up the line,and to accomplish the conjoint purpose by forming the spring-connectionitself as a turn-buckle. To this end I employ two coiled springs, onecoiled to the right and the other to the left, connecting one of saidsprings to the support and the other to the wire, or whatever it may be,and uniting these springs by a central rod or spindle, having at eachend a spiral flange or wing, 0 turning respectively to the right and tothe left and adapted to enter between the coils of the springs and beadjusted therealong by turning the spindle, thus taking up slack, orletting it out to tauten the line or relax it, as 5 may be foundnecessary, all as fully set forth in an application filed by me on the28th day of August, 1889, Serial No. 322,262, for Letters Patent of theUnited States for an improvement in ways for cash and parcel carriers,of which this is a division, and patented to me January 12, 1893, as No.490,093.

My inven tion, therefore, may be said to consist in a springturn-buckle.

In the drawings: Figure 1 is a side eleva- 5 tion of assembled mechanismconstituting a turn-buckle constructed according to my invention. Figs.2 and 3 are eye-bolts or rods with rightandleft threads to enterbetweenthe outer coils of the springs and serve as means 5c of attachment tothe support and line. Fig. 4

represents the central rod or spindle having right and left threads atopposite ends; Figs.

5 and 6, right and left coiled springs detached from the othermechanism, and Fig. 7, an enlarged transverse section or end view of oneof the eye-rods or of the central spindle, showing the thread thereon.

A represents a right hand, and A a left hand coiled spring. Each ofthese is to be attached at one end to one of the members intended to beunited; that is, in the case of a wire or other line, one of them willbe attached to said line and the other to the support or part to beconnected by the line with a distant point. The means adopted forfastening these ends to the respective parts that they are intended tounite, maybe of any suitable description, but I prefer to employeye-rods, B and B, the first having a right hand thread, b, and thesecond a left hand thread, h, adapted to enter between the coils of thespring and screw therealong. These eye-rods, except for that partintended to remain permanently outside of the coils, are cylindrical, asat W, and of such diameter as practically to fill the internal walls ofthe coils, thus insuring a firm grasp of the threads. The threadsthemselves may have any suitable shape adapted to hold against the coilsand will be pointed at the advancing end to enter readily between saidcoils and may, with advantage, be pointed at the retreating ends. Theyalso may be advantageously somewhat undercut partially to embrace andsaddle the wire, thus insuring against slip in the axial direction. Whenthe eye-rods have been turned so as to bring within the grasp of theirthreads two or three of the coils, they will be so firmly secured to thesprings that they can not be pulled off without breaking go the wire orstraightening out the coils. They may then be attached to the support orto the line as the case may be; or conversely they may first be attachedto the support and to the line, or whatever is to be connected, and nthe coiled wire springs themselves screwed l upon them.

C is a central rod having at one end a right hand thread, 0, and at theother end a left hand thread, 0, the characteristics of these toothreads being the same as those of the threads upon the eye-rods and thediameter of the cylindrical parts, 0 of the rod being the diameter ofthe internal walls of the spring coils. This central rod is intended tounite the two springs by screwing therein. It is or may be square, orpolygonal in cross section, at its center, as at 0 for the use of awrench or spanner, or it may be roughened for the grasp of the hand orfingers, depending upon the strength of the springs, the power necessaryto be applied and the tension it is desired to secure by means of theturn-buckle. Now, applying this central rod to the coiled springsalready attached to their supports and lines, the right hand thread willbe introduced between the right hand coils and the left hand thread willbe introduced between the left hand coils, and then, by turning the rod,the springs will be drawn to any desired tightness, tautening the wireor other line, and yet leaving it a certain resiliency which will takeup shock or strains that otherwise might break it.

It is evident that instead of two coiled springs with a central rod, 2.single coiled spring may be used, screwing upon fixed rods or spindlesat each end, right or left hand threaded, according as the coils areright or left hand.

I clain1- 1. The spring turn-buckle, herein described, consisting of twocoiled springs having right and left turns respectively, and a centralof said springs.
